The result is an extraordinary end-to-end mobile experience with the best value for money.”

Samsung didn't mention pricing or availability for the REX line, but the company plans to offer these phones in emerging markets with low price points.

you say this, but my htc desire is a smartphone, albeit getting on in adys, but i recently bought a new battery, and with wifi off, and using it as nothing but a kitchen timer and say 10 texts, it will be lucky to last me 24 hours. I've an old sony w850i i think it is, that i've had for donkeys years, and with the original battery, i'll still get a few weeks use from is for timer/flashlight/texts

I also own a HTC Desire. My first and currently only smartphone. And with moderate usage (like on a boring weekend at home, occasional checking mails, checking time, short web surfing), with Wifi on, mobile data off, I can get 3 days or more of usage, with the 2.5 years old battery I used from day one. With normal usage, talking, browsing, mobile data on, it lasts over one day, up to max. two. With heavy usage, playing games, full brightness, it's empty in less than half a day.Most probably it's because I use a custom ROM based on CM, or maybe it's because you have mobile data, GPS or other devices turned on?But your point is valid, the battery life of the HTC Desire in default configuration is nothing spectacular, but also remember it was one of the first Android smartphones and is far from perfect.
